Deprecated features
No features were deprecated in this release.
Known issues:
- The following operators:
experimental.readers.fits
,experimental.decoders.video
, andexperimental.inputs.video
do not currently support checkpointing. - The video loader operator requires that the key frames occur, at a minimum, every 10 to 15 frames of the video stream.
If the key frames occur at a frequency that is less than 10-15 frames, the returned frames might be out of sync. - Experimental VideoReaderDecoder does not support open GOP.
It will not report an error and might produce invalid frames. VideoReader uses a heuristic approach to detect open GOP and should work in most common cases. - The DALI TensorFlow plugin might not be compatible with TensorFlow versions 1.15.0 and later.
To use DALI with the TensorFlow version that does not have a prebuilt plugin binary shipped with DALI, make sure that the compiler that is used to build TensorFlow exists on the system during the plugin installation. (Depending on the particular version, you can use GCC 4.8.4, GCC 4.8.5, or GCC 5.4.) - In experimental debug and eager modes, the GPU external source is not properly synchronized with DALI internal streams.
As a workaround, you can manually synchronize the device before returning the data from the callback. - Due to some known issues with meltdown/spectra mitigations and DALI, DALI shows best performance when running in Docker with escalated privileges, for example:
privileged=yes
in Extra Settings for AWS data points--privileged
or--security-opt seccomp=unconfined
for bare Docker.
Binary builds
NOTE: DALI builds for CUDA 12 dynamically link the CUDA toolkit. To use DALI, install the latest CUDA toolkit.
CUDA 11.0 and CUDA 12.0 builds use CUDA toolkit enhanced compatibility.
They are built with the latest CUDA 11.x/12.x toolkit respectively but they can run on the latest,
stable CUDA 11.0/CUDA 12.0 capable drivers (450.80 or later and 525.60 or later respectively).
However, using the most recent driver may enable additional functionality.
More details can be found in enhanced CUDA compatibility guide.

Breaking API changes
- DALI 1.39 was the final release to support the MXNet integration.
Deprecated features
No features were deprecated in this release.
Known issues:
- Starting with DALI 1.39, a performance regression was observed in hardware-accelerated image decoders for setups with high number of worker threads. The nvImageCodec hardware decoder pre-allocation uses higher mini-batch size, causing extra cuMemFree calls that may slowing down decoding in some iterations. The issue will be fixed in the upcoming release.
- The following operators:
experimental.readers.fits
,experimental.decoders.video
, andexperimental.inputs.video
do not currently support checkpointing. - The video loader operator requires that the key frames occur, at a minimum, every 10 to 15 frames of the video stream.
If the key frames occur at a frequency that is less than 10-15 frames, the returned frames might be out of sync. - Experimental VideoReaderDecoder does not support open GOP.

Breaking API changes
There are no breaking changes in this DALI release.
Deprecated features
No features were deprecated in this release.
Known issues:
- The following operators:
experimental.readers.fits
,experimental.decoders.video
,experimental.inputs.video
, andexperimental.decoders.image_random_crop
do not currently support checkpointing. - The video loader operator requires that the key frames occur, at a minimum, every 10 to 15 frames of the video stream.
If the key frames occur at a frequency that is less than 10-15 frames, the returned frames might be out of sync. - Experimental VideoReaderDecoder does not support open GOP.
It will not report an error and might produce invalid frames. VideoReader uses a heuristic approach to detect open GOP and should work in most common cases. - The DALI TensorFlow plugin might not be compatible with TensorFlow versions 1.15.0 and later.
To use DALI with the TensorFlow version that does not have a prebuilt plugin binary shipped with DALI, make sure that the compiler that is used to build TensorFlow exists on the system during the plugin installation. (Depending on the particular version, you can use GCC 4.8.4, GCC 4.8.5, or GCC 5.4.) - In experimental debug and eager modes, the GPU external source is not properly synchronized with DALI internal streams.
As a workaround, you can manually synchronize the device before returning the data from the callback. - Due to some known issues with meltdown/spectra mitigations and DALI, DALI shows best performance when running in Docker with escalated privileges, for example:
privileged=yes
in Extra Settings for AWS data points--privileged
or--security-opt seccomp=unconfined
for bare Docker.
Binary builds
NOTE: DALI builds for CUDA 12 dynamically link the CUDA toolkit. To use DALI, install the latest CUDA toolkit.
CUDA 11.0 and CUDA 12.0 builds use CUDA toolkit enhanced compatibility.
They are built with the latest CUDA 11.x/12.x toolkit respectively but they can run on the latest,
stable CUDA 11.0/CUDA 12.0 capable drivers (450.80 or later and 525.60 or later respectively).
However, using the most recent driver may enable additional functionality.
More details can be found in enhanced CUDA compatibility guide.

Breaking API changes
There are no breaking changes in this DALI release.
Deprecated features
No features were deprecated in this release.
Known issues:
- The following operators:
experimental.readers.fits
,experimental.decoders.video
,experimental.inputs.video
, andexperimental.decoders.image_random_crop
do not currently support checkpointing. - The video loader operator requires that the key frames occur, at a minimum, every 10 to 15 frames of the video stream.
If the key frames occur at a frequency that is less than 10-15 frames, the returned frames might be out of sync. - Experimental VideoReaderDecoder does not support open GOP.
It will not report an error and might produce invalid frames. VideoReader uses a heuristic approach to detect open GOP and should work in most common cases. - The DALI TensorFlow plugin might not be compatible with TensorFlow versions 1.15.0 and later.
To use DALI with the TensorFlow version that does not have a prebuilt plugin binary shipped with DALI, make sure that the compiler that is used to build TensorFlow exists on the system during the plugin installation. (Depending on the particular version, you can use GCC 4.8.4, GCC 4.8.5, or GCC 5.4.) - In experimental debug and eager modes, the GPU external source is not properly synchronized with DALI internal streams.
As a workaround, you can manually synchronize the device before returning the data from the callback. - Due to some known issues with meltdown/spectra mitigations and DALI, DALI shows best performance when running in Docker with escalated privileges, for example:
privileged=yes
in Extra Settings for AWS data points--privileged
or--security-opt seccomp=unconfined
for bare Docker.
Binary builds
NOTE: DALI builds for CUDA 12 dynamically link the CUDA toolkit. To use DALI, install the latest CUDA toolkit.
CUDA 11.0 and CUDA 12.0 builds use CUDA toolkit enhanced compatibility.
They are built with the latest CUDA 11.x/12.x toolkit respectively but they can run on the latest,
stable CUDA 11.0/CUDA 12.0 capable drivers (450.80 or later and 525.60 or later respectively).
However, using the most recent driver may enable additional functionality.
More details can be found in enhanced CUDA compatibility guide.
